PCD grinding solution


2021-08-27


PCD (Polycrystalline Diiamond) is a kind of polymer sintered by artificial diamond powder under high temperature and high pressure, also known as Polycrystalline diamond.Same as single crystal diamond, with high hardness and wear resistance characteristics.

The difficulty of PCD processing:

PCD material because of its high hardness, the processing process is easy to produce high temperature, high hardness also makes the grinding processing efficiency is not good, so it is difficult to grind materials.

★ Abrasive selection:

To be able to process PCD materials, it is necessary to choose an abrasive with higher hardness than it, so we can only choose the super-abrasive grinding wheel with diamond or cBN abrasive.

★ Binding agent selection:

However, super abrasive grinding wheel is mostly resin bond, but if facing PCD material, ceramic bond will be more suitable.Because the ceramic bond can produce more pores when sintering, and the ceramic heat resistance is good, sharp cutting, so it is not easy to heat and expansion.When grinding with high hardness, the grinding efficiency and precision will be higher than that of ordinary resin diamond grinding wheel.

Therefore, to process PCD materials, the most appropriate choice is the use of ceramic bond superabrasive grinding wheel.

Demina PCD tool grinding wheels can meet the features of PCD processing. Welcome to inquiry our company. As a tool grinder manufacturer, we can provide high quality PCD tool grinding wheels.
